-----
The patch changes NativeCall to use IdScriptable. This is done mostly
for uniformity with other Native* classes plus it would allow to call
NativeCall.init directly and make NativeCall package private.
-----
The patch changes NativeScript to use id-based properties. Due to
inheritance from NativeFunction, id support requires to take into
account the fact that there are instance ids available from
BaseFunction. This is the reason to use "int prototypeIdShift" instead
of "boolean prototypeFlag" so it can store instance id offset.
The patch updates ScriptRuntime.callOrNewSpecial to check against
IdFunction and not FunctionObject for the Script exec method where it
also add finally clause to make sure that Context.exit would always be
called after Context.enter in the evalScript method.
-----
After converting NativeScript and NativeFunction to use IdScriptable,
they get scope argument directly as a parameter of execMethod call, so
cx.ctorScope is not used any more. The patch removes code to set/unset
cx.ctorScope.
-----
[This patch depends on conversion of NativeScript and NativeCall to use
IdScriptable and the patch to remove access of ctorScope from
FunctionObject]
The patch changes Context.initStandardObjects to call NativeCall.init
and NativeScript.init directly plus it unrolls the lazily initialization
loop. Due to rather poor support of an array initialization in Java byte
code, it actually decreases code size while eliminating are creation of
array object. The patch also removes ctorScope field as unused.
-----
The patch makes sure that ids used by NativeGlobal are visible only in
the object instance that initializes global scope and removes some junk
white space at line ends.
-----
To use the idswitch tool to generate map for strings that can not be
part of Id_ Java identifier like $*, I added code to the tool to look
for "// #string=...#" in the id definition line. The attached README
file also contains some documentation about the tool and should go to
idswitch directory.

to grows, shrinks, and compresses. This helps JS_DHashTableOperate callers
who hold returned entry pointers to validate those pointers and avoid having
to re-lookup an entry by its key.
- Balance that addition by removing JSDHashTable.sizeMask, which is induced by
JSDHashTable.sizeLog2 at the cost of two typically single-cycle instructions.
- Use JSDHashTable.generation in jsobj.c to avoid unsafely dereferencing an
entry pointer held across calls to JSClass.resolve from js_LookupProperty,
which may recur and add entries to cx->resolving, growing that table and
invalidating entry pointers held by earlier js_LookupProperty activations.

The patch changes Notification to extend from BaseFunction and adjusts
Context, FunctionObject and NativeScript accordingly.
----
The patch changes BaseFunction.jsConstructor to use the scope argument
passed to execMethod instead of using cx.ctorScope. This argument is
null in this case because when calling execMethod IdFunction.construct
does not set cx.ctorScope because scope is passed to execMethod as argument.

in fields of the object itself instead of using the standard property
hashtable in ScriptableObject.java. This saves 3 object instances per
NativeError (2 slot entries and hashtable array itself) and given the
fact that NativeGlobal defines a few permanent Error instances, it is
visible saving even after taking into account code size increase.
The change also gives a good test of IdScriptable implementation.
-----
This patch introduces the uniform decompile method for NativeFunction
and IdFunction with the signature:
public String decompile(Context cx, int indent, boolean justbody)
instead of NativeFunction.decompile(int indent, boolean toplevel,
boolean justbody) and IdScriptable.toStringForScript(Context cx) and
replaces the special treatment of NativeJavaMethod in
NativeFunction.jsFunction_toString by overriding decompile in
NativeJavaMethod

Rhino: behavior update for IdScriptable subclasses

The attached patch introduces separation between id-base properties in
prototype instances and the rest of objects so it is possible to
allocate some ids for each instance and the rest only for prototype. The
patch adds to each descendants of IdScriptable a special prototypeFlag
which set to true only if object serves as a global prototype and all
methods that check/return ids first check for that flag. (This is the
reason for the patch size: diff is not very well in dealing with
indentation changes.)
In this way ids for prototype properties are completely hidden from
potential subclasses and there is no need to define methods like
getMaximumId in most cases, only if some ids present in each instance,
IdScriptable.maxInstanceId should be overridden to return max id present
in each instance.
The patch also replaces 2 boolean fields in IdScriptable by bit masks in
the setupFlag field.

Hello, I am trying to find a scripting language with an interpreter that I
can embed in an applet in order to run test scripts inside the applet. I
have already tried TCL-based Jacl and they do not support running inside an
applet. I then downloaded the Rhino/JS interpreter but am having trouble
getting it to run inside the browser (IE 5.5). Here is the exception I am
getting:

1. In that patch I forgot to remove "import org.mozilla.classfile.*" and
simply catch Exception in newInvokerMaster which is not a good practice.
The attached patch FunctionObject_patch fixes that and removes other
unused imports.
2. In org.mozilla.classfile.DefiningClassLoader defineClass method first
tries to call via ClassManager the defineClass method in a class loader
that loaded DefiningClassLoader itself. But this would define new
classes in that class loader so they would not be subject of the garbage
collection until a classloader that loads DefiningClassLoader would go
away even if a DefiningClassLoader instance is gone. The
DefiningClassLoader_patch removes that and simply calls super.defineClass.
The patch also change the order of class search in loadClass so the
loader first looks for a class among its defined classes and only after
that in parent loaders.
Regards, Igor
